sounds like glow plug relay is hung up

glow plugs
injectors blocked

There a small plug with wire on it right a round injectors. Take 5/16 socket ( i think) screw it out

all fuses and relays under seat in foot control area

That unit runs on diesel. The click could be a fuel pump relay or injector pump or injectors retracting.

Could be engine speed sensor. All fuses need to be checked. Any smoke when cranking? Any fault codes? A bad fuel solenoid could cause no start if fuel is good.

The first thing to do is locate the owner manual.

Look for the glow plug relay MAIN FUSE location.

The glow plug portion of your van is not working.

This difficulty scale from 1 to 10 is a 9.

You will need a DVM and tool undo the cables to each glow plugs.

It's a 1 to 2 hours troubleshooting job.

I'm going to fire off a quick list

====
Check / replace blown glow plug relay main fuse
====

Disconnect each center nut of the glow plug wire. PLEASE CHECK ONE AT A TIME.

Read the resistance between the center of the glow plug and the metal base of the plug.

Please take good note on each glow plug resistance reading.

MAKE SURE all cables are put back and tighten properly.

Compare the resistance on all cylinders.

OPEN/high resistance is bad glow plug.

In general 3 ohm or less is OK.

You should buy one and use its value as baseline.

===

Glow plug relay can be bad.

You will need the VOM and a friend to turn the key.

Check the voltage to each glow plugs. It should be 12.6-13.6 volt.

Be careful,the plugs will get HOT.

Compare the voltage on each cylinders.

====
So the problem can be combination of

glow plug relay

glow plug relay main fuse

glow plugs

ignition switch is unlikely but I'm going to list it anyway.

Once again,this is a difficult and time consuming job. I will ask a friend to help out,

Good luck.

replace the relay but check connections first as often connection get hot and corroded.failing which buy a push button switch use a relay and and some heavy wire to and from relay to the heaters and work them manually.you could try seperating the relay and cleaning the connections inside.
